Crack Monitoring
Continuous Crack Monitoring for Walls, Ceilings and Floors
Sub-millimetre tracking of crack width and behaviour over weeks and months , so you know whether each crack is stable, seasonal or accelerating.
Cracks are notoriously difficult to read with the eye alone. A 1 mm crack today might still be 1 mm in twelve months , or it might be the visible tip of something getting steadily worse. Without continuous measurement, surveyors and owners are forced to make repair decisions on snapshots and guesswork.
Our crack monitoring service settles the question. We install precision displacement sensors directly across each crack of concern, then capture how its width changes through the day, week, month and full seasonal cycle. The output is a defensible, time-stamped record of behaviour , not a one-off opinion.
Whether you're a homeowner with a recent crack of unknown cause, an insurer validating a subsidence claim, or an engineer signing off remedial works, the question is the same: is this crack moving? Continuous monitoring is the only reliable way to answer it.
What we monitor
Every kind of crack , read in sub-millimetre detail.
We instrument cracks across virtually any material and orientation, and interpret patterns that tell you what the building is actually doing.
Hairline vs structural cracks
Distinguishing between cosmetic shrinkage cracks and progressive structural movement is the single most useful outcome of monitoring.
Vertical, horizontal & diagonal
Direction matters. Diagonal stepped cracks across brickwork suggest different mechanisms to vertical cracks above openings.
Seasonal behaviour
Many cracks open and close with temperature and ground moisture. A full year of data separates seasonality from genuine movement.
Internal & external
Sensors work indoors on plaster and render, and outdoors on masonry, brick and concrete in all UK weather conditions.
Multi-point per crack
Long or branching cracks are monitored at multiple points so you can see whether movement is uniform or localised.
Independent & defensible
We don't sell repair work , only evidence. Readings are time-stamped, auditable and accepted by engineers and insurers.
Process
A repeatable, measurable approach.
Site assessment
We review photographs, prior reports and access. A scoping call confirms how many sensors and where.
Discreet installation
A single visit, typically under two hours, with non-intrusive fixings and minimal disruption to occupants.
Continuous capture
Sensors record sub-millimetre readings automatically each day and stream them over cellular comms , no site Wi-Fi needed.
Reports & alerts
Live dashboard, threshold email alerts, and clear PDF reports for engineers, insurers or owners.
